This document discusses seismic hazards in Egypt. It covers deterministic seismic hazard analysis (DSHA) and probabilistic seismic hazard analysis (PSHA), defines seismic zones, and lists major earthquakes and faults. It also discusses the distribution of earthquakes in Egypt, noting that most are between magnitudes 5-6, some below 4, and provides an equation to describe earthquake frequency as a function of magnitude.

Log(N) = a –b M
N= number of earthquakes with magnitude
equal to or greater than m
M= magnitude
a and b are model parameters related to
level of seismicity and tectonics respectively
